Unreachable by man, scientists have developed a complex experiment to demonstrate the heat and pressure at the center of the Earth.
- The Earth's core is a dense ball of iron and nickel.
- To recreate the conditions of the Earth's core, scientists developed a hydrogen gas gun.
- The hydrogen gas gun emulates the pressure of the center of the Earth on an iron projectile.
- Scientists measure the heat at the point of impact, revealing the Earth's core to be at least 6200 degrees centigrade.
The Earth's core is a mysterious place.
About 2900km below the planet's surface, the core is a dense ball of iron and nickel.
As the Earth rotates, the molten outer core spins around the solid inner core, causing the Earth's magnetic field.
Magnetic field created by:
Molten outer core
Solid inner core
The core's ...
